ORCHARD-HEATING DEVICE.

eene-e2.'

To all whom it may concern-:I Be it known thatv I, PERCIVAL-HAMMER TROUTMAN, a citizen ofthe United States,

'- residing at Canon City, county of Fremont,

My invention v'relates' tofimprovements in devices for' heating orchards, or 'other lo `calities, 'to prevent injury from frost.

My. improved device consists of a reservoir adaptedy to hold liquid fuel and av centrally located casing forming a combustion chamber which-is separated from the sur-` rounding fuel in they reservoir, vthe lower extremity of the said casing being notched or recessed-to allow the liquid fuel rto enter the combustion Achamber at thel bottom. This casing is..attached to the tbp of the reservoir and .is removable therewith.- The the reservoirandhaving a ydrafto emng bottom of the reservoir is provided with a centrally located opening surrounded by a chimney, which projects upwardly -therefrom. When the .parts are assembled, this chimney is inI thecenterof the combustion chamber or the casing which forms said .'chamber." By means of the chimney, provision is made for aA center draft upwardly` through the combustion chamber,thus' facilitating the burning of the-liquid fuel.A The lreservoir is preferably (supported a suitable. distance above the ground or other .surface upon which it rests, by means of -a -.base extending downwardly from the bottoni; of

controlled by a' slide whereby air is a owed to enter the baseand pass upwardly through' the chimney, which isopen at both ends.- Tov prevent the heat in the combustion chamber from unduly raising the-'temperature of the oil, or'otherliquid fuel in the reservoir, the outer portion of the casing is ypreferably provided with'an auxiliary wall spaced from the main wall of the casing.

formingan air chamber, whereby the C11 within? the Ireceiver is insulated from the' combustion chamber.

l Having :biey outlined my construction, I Will proceed to describe the.

the

samev in detail, reference beingmade 'to accompanying drawing in which is1illus-v trated an embodiment thereof.4

. In this drawing, Figure 1 is a central vertical 'section taken through my improved orchardheating device, 'showing the same complete and in use. Fig-2 is a similar section, taken throu h the reservoir, the casing Specification of Letters Patent. Patented 4Jun@ i4.' 1910.

forming the com ustion chamber being re -m0ved Fig/3 is a horizontal section taken through the device on the line 3-3, Fig. 1. Fig. 4 is a sectional detail v iew ofthe combustion chamber and the reservoir top.

The', same reference characters' indicate the same parts in all the views. -Let the vnumeral 5 designate the reservoir considered in its entirety. I This reservoir is 'provided with a base 6, which extends below its` bottom 7. -In this base is formed an air opening 8 controlled Vbya slide 9 moving 1n grooves l0 which are indicated Aby dotted lines.l The bottom of the reservoir'is pro- .vided with a centraljopening 12 from which extends upwardly achimney 13, which is preferably frustum-shaped, being'larger at the-bottoni than at the top. Bothextremiti'esvv of this chimney are o en.y Near the topand above t-he yliquid fue 14, the chimney may be perforated, as shown at l5.- Centra'lly locatedin the reservoir, and surroundl ing the chimney 13, is a casingl 16, whose lower edge is notched, as shown at 17, to- I allow ...the liquid fuel to\enter"the casing,

chamber. 'To thisl casing is secured a; cover provided exteriorly 1with an auxiliary wall 18, which' is spaced from the casing, form? v .which, as aforesaid, constitutes a combustion .20 vfor 'theo reservoir. The casing is also in the reservoir'from the combustionchamf ber.-

`When the device is in use the parts `are assembled, as shown in Figs. 1 and 3. -A

suitable uantity of oil orfother liquid.

may be p aced-i'n the reservoir, after which thecasing forming the combustion chamber, together with thecover, are put in position. Or, the parts may be vrst assembled, after which-the liquid -fuel maybe poured .into

the combustion chamber, whence it .readily passes into the surrounding.l portion of the reservoir through the openings '17 at the.`

bottom of the casing. The fuel withinthe combustion chamber is then lighted vin any ,suitable manner, and as it burns it is rellt) plenished from the surrounding body of oil within thereservoir; The latter may be of any suitable size.

The insulating wall 18, with which .the casing 16'is provided, also' serves to prevent the liquid fuel within the combustion chamber from becoming unduly cooled by the surrounding body of liquid fuel, in case the latter should be of a temperature sutciently low to1 have a cooling effect. It will thus b`e understood that this partition performs the double function of insulating the oil-in the combustion chamber from the cooling influence of the surrounding body of oil, and also of preventing the temperature 'surrounding the body of oil from becoming undulyraised by the heat of the combustion chamber. n

Having thus described my invention, what I claim is: ,n

1. An orchardvheater comprising a fuel containing reservoir having an opening in the bottom thereof, a centrally located openended chimney communicating with the said opening,`said chimney extendinof upwardly through said reservoir, a verticaIly disposed partition located in the reservoir and formfr ing a combustion chamber around the chim ney, the said partition having openings in. the bottom through which fuel is fed to the combustion chamber, a second partition vertically disposed around said combustion chamber and forming an insulatingchaml ber between the combustion chamber and the fuel in the reservoir, and a support for the reservoir, the said support constructed to allow `air to enter the chimney, substan-` 'the fuel containing reservoir, acover for t-he reservoir carried by the said partition, the' said cover also formi-ng Va closure for the insulating-space, and asupport extending below the bottom of the reservoir, the said support being constructed to /allowair to enter the chimney for draft purposes, substantially as described.

In testimony whereof I my signature in presence of two witnesses.
